a The immune cell infiltrating score evaluated by time-dependent ROC curves at 1, 3 and 5 years in the training cohort. The area under the curve at each time point was 0.674, 0.684 and 0.675, respectively. b Survival analysis stratified by immune cell infiltrating score in the training cohort (P < 0.001). c The immune cell infiltrating score evaluated by time-dependent ROC curves at 1, 3 and 5 years in the validation cohort. The area under the curve at each time point was 0.650, 0.616 and 0.567, respectively. d Survival analysis stratified by immune cell infiltrating score in the validation cohort (P = 0.013)
